PFF5-1322 Poly Mount Insert for BMW and MINI - Driveline Support Upgrade

Get crisper gear changes and a more connected drive with the Powerflex PFF5-1322 transmission support insert. This precision polyurethane insert in 70 Shore A fills the voids in the original rubber mount to steady the drivetrain under load, improving shift feel, traction off the line and steering response without the cost of a full mount replacement. Perfect for daily performance and spirited road use on BMW and MINI platforms that share the same mounting layout.

Why enthusiasts choose this upgrade

• Stabilises the transaxle and reduces unwanted movement during acceleration, braking and cornering
• Sharper gear engagement and improved throttle-to-chassis connection
• Durable polyurethane compound resists oil, heat and ageing far better than soft OE rubber
• Cost-effective insert solution - keeps the factory mount housing while removing excess compliance
• Quick install with minimal downtime - 1 insert required per vehicle
• Trusted brand quality from Powerflex, proven on UK roads

We have installed this part in-house and customer feedback has been excellent, with consistent reports of tighter driveline control and noticeably cleaner shifts on both stock and mildly tuned cars.
